-and useful Improvements in Sparking Igniters,of which the following is a. full, clem', and exact description. y

This invention relates to igniters or lighting devices of the t pe in which an' ebrdding element is canse to operate upon n bod of sparking material, such es en alloy of iron and cerium, to produce e. shower orl stream (5f-sparks which, upon meeting any iniicmmablegas or vapor, `will ignite they, same. e A

The chief object of the invention is to provide an improved device of this class, par-- ticularly in the direction of certainty end uniformity of operation. l

Aurther object is to `provide a device inwhich the working with the exception of the abrading felement, the manual actuating member and the sparking body, are inclosed, without materially increasing the bulk of the article, thereby making the device more leasing in appearance es well es more dura. le.

Te these and other ends the invention consists in the novel features of construction and combinations of elements 'hereinafter described.

One lform of the invention is illustrated in the eccompanyin drawings, in which-'- ligure 1 shows e device in side elevetion, attached to on ordinaryr ges burner.

. Fig. 2 is s vertical section of the device.

A line 5-5 of Fig. 2.

Fig. 3 is a side view, with the 'outer casing in section 0n line 3L-3 of Fig. 2. .Fig. 4 is c top plan view. Fig. 5 is ecross sedsion on The outer casing 10 is in the form of e. hollow cylinder, and serves both es en in closure and as e bearing for en roteteble driving member or body com csed of e cylindricol spring-chamber or hol c1111 and e heed 12, also cylindrical'. The perte 11 end 12 are rigidly connected together, as

. 'by s pin 13. 'In the' bottom of the springk holder or chamber is a, rotatable-,plug 11i resting on e flange 15 on the inside of the casing 10, seid plu having a stem 16 to which the ectuatingxendle 17 is detechably connected, as shown. On the top of the I plug is e boss 18, exiellyalined with e boss 19 depending from the head 12. These ,plug and the heed, as shown. it will theretore he seen that the head end`- the plug are yieldingly connected, so that if the letter lis turned (for example in the clcckvvise'di- .the heed will be urged in the seine direction.

In the topof the casing 10 is e bearing 21, held in place by e screvv 22 and rabbeted st its lower e d to fit the shoulder 23 on the stem 24, w ich is ireely rotatable in the `bearing but tv' 'eh can not move axially .on account of sei rebbet and shoulder. The lower end 25 qf'the stern is cared, to fit 'c square socket 26 in the hec. i12. Hence, \when the plugi 14 is tnrned as described yabove it tends "to rotate not only the heed 12 but .the'stem or shaft 24 also. Rigidly hardened steel having en ebrading edge in contact with e small cylinder 28 of sparking material. The letter is supported by a. hollow carrier 29, fastened to the casio 10 by means of the screw 22, and is held yidingly against the ebredin disk or wheel by a hel1- cel spring 301insi e the aforesaid carrier. A screw plug 31 in the outer nd of the carrier serves to regulate the ension of the .ing body on the abra ng w Ieel 27. It will therefore be seen .that rotetin of the head 12 under the induence f spi'ing 20 Willrotate the disk 27 in contact with the s arking body, thereby producing a. stream o sparks from the letter.

of the bearing 21, ere not tiet; but instead, one o' them, for examplejthe head 12, 1s

corresponding recesses or notches in the oontignous fece of the other. nasmnch es the bearing-21 is not rotatable, it will be Seen that tension onthe spring 20 will not ro tete the heed 12, the shaft or stem 2li, and .the obreding disk 27, unless the said head 'elly in tje casing 10 to unlock the head from the xed bearing. For the purpose of thus depressing the parts nam( l. the lower end 'of the spring-holder 11 is provided with e. wide :and rather deep notch 33, forming 'at Patenten July e1, ieri.

spring und hence the ressure of the spark- The top of the heed 12, hud the bottom provided .with one or morelugs 32 fitting ond the s ring-carrier 11` are depressed axione end a bayonet slot 34 and at the other having an inclined cam-edge In assembling the parts, thespring 2O is tensoncd so as to hold against the end of the baymietslot the small stud 3.6 on the Side of the plug 14, shown in Fig. 3. Now when the plug is turned in the clockwise direction (as seenfrom the bottom of Fig. 2) it tends to rotate the stem or shaft 24 and disk 27, but is prevented by the interlocking of the head 12 and the stop-bearing 2l. Hence the result is that at first the plug alone is turned, thereby moving the stud 36 away from the abutting vertical edge of the bayonet slot 34. Eventually the stud comes against the cam-edge and, since the plug cannot move axially because of the flange 15 and the increasing aressure of the spring 20, the result is that t e pin coperating with the cam-edge 35, causes the body 11--12 to move axially downward. This unlocks the head 12 from the stop 21, whereupon the tensioned spring instantly rotates the body 11--12, shaft 24 and disk 27, until the verti-` cal edge of the bayonet slot 34 strikes the stud 3G. At the same time the lugs 32 again reach the locking notches in the stop 21 and are caused to enter the same by the upward pressure of the spring 20.

From the foregoing it is seen that the effect of turning 'the lug 14 is to tension, or store up power in, t e spring 2,0, and that when the tension of the latter reaches a certain amount, always the same, thev spring is automatically released. Also, the rotary movement of the abrading disk is always lthe same in extent. Hence the operation of the vdevice is always uniform.

Another important advantage lies in the toothed abrading edge of the disk 27. As will be seen in Fig. 4, the edge is nottoothed around its entire circumference but only in sections, leaving smooth non-abrasive portions between the toothed portions. In assembling the device the squared boss 25 is so inserted in the Socket 26 that the disk 27 will normally stand with a smooth portion of its edge on the left of the sparking body 28, as shown in Fig. 4. Then when the disk begins to rotate, a smooth portion first passes the sparking body, thereby allowing the disk to acquire speed before it begins to abrade the body. This causes the -succeeding toothed portion to strike the body with greater speed, thus producing a more abundant stream of sparks than would othcrwise'be the case. l prefer to have the parts so designed and coixstructed as to give the disk a half-revolution at each operation, in which case the toothed portions are diametrically opposite to each other and are preferably each about 90 in extent, as shown in Fig. 4.

To hold the device in proper relation to a gas burner or the like, it is provided with a suitable clamping device 37 having jaws to encircle an appropriate part of the burner lind provided with a binding bolt 3S.

It is to be understood that the invention is not limited to the particular construction herein specifically illustrated and described, but can be embodied in other forms without departure from its proper spirit and scope.
